A maintenance release of VisiWave (v6.0.3 ) is now available for download. If you already own v6.0 of VisiWave, just download the eval version and install it over-top of your current version. Your existing license will continue to work. If you would like to evaluate VisiWave, just download the eval version and try it out.

New features in v6.0.3:

• Door & Window Issue With Predictive Surveys

  In some rare cases, the order that doors or windows are included was causing VisiWave to hang. The ordering is now changed automatically.

• View in Chanalyzer Issue with Large Datasets

  VisiWave had an issue when using the View in Chanalyzer feature when the range included too many data points.
  Chanalyzer would load but no data would be included. This situation is now fixed.

• Google Earth Report Default Extension

  If a file extension wasn't provided for the report file, the file was given the extension of KML. But it needed to be KMZ for the Google Earth files VisiWave creates. An extension of KML would cause the embedded images to display as large X's.

• Google Earth AP Coverage Maps Issue

  If you generated an AP Coverage map for Google Earth and had both "What to Map" set to "Strongest" and "Highlight Overlaps" set to anything other than "None", then VisiWave couldn't generate the Google Earth report. Note that there are never highlighted overlaps when mapping the strongest APs so usually this wasn't an issue.

New features in v6.0.2:

• Set GPS Location Issue

  If "Get Location from GPS Device" was selected from the "Set GPS Location" menu item before any data was collected, then the program would crash.

• Channels Under Noise Can't Be Selected When First Adding Spectrum Data

  In Survey View in the right pane, the 2.4GHz and 5GHz channels under "Noise" can't be selected when you collect the first set of spectrum data points. The channels remained grayed out.
  You had to save the survey file and re-load it before you could access the noise channels.

• Predictive Heatmap Issue with Large Survey Areas

  A large survey area (50m on a side or more) could have had issues producing accurate predictions when the radio was placed near the top of barriers. The simulation had a path over the barriers which was making the signal strengths too generous.

• Channel Maps Weren't Handling Some In-Between Channel Numbers

  Some channels that were "wide" (40MHz, 80MHz, or 160MHz) couldn't be selected in a Channel map. Now VisiWave handles all common channel numbers regardless of channel width.

• Rotate Horizontal Wasn't Working for Dipole Antennas

  For predictive surveys with radios set to have dipole antennas, the Rotate Horizontal setting wasn't affecting the heatmap pattern. It is now functioning correctly.

• Predictive Heatmaps Had White or Gray Regions

  With a few combinations of Min and Max color legend settings, some regions of the colored heatmap would show up as white or gray when they should be a dark red (when using the default
  color scheme).

New features in v6.0.1:

• Added Support for Channel Bonding in Predictive Surveys

  When doing a simulation, you can now set a radio's channel width in addition to just its frequency in the 5GHz band.
  You do this by right-clicking on a radio and selecting Edit Radio. This allows you to simulate the effects of channel bonding. For example, you can select channel 36 and say that it is a 40MHz channel to bond channels 36 and 40 together.

• Issue Fixed with Exporting Simulation Data to CSV

  VisiWave was exporting only half the simulated signal values to the CSV file. Every other value in the X direction was skipped. Now all the values are exported.

• Performance Improvements When Selecting Radios in Predictive Mode

  There were a few cases where updating the heatmap in Predictive mode took much longer than needed.

• Allow Merging of Survey Files When Floor Plan Sizes are Slightly Different

  Due to some rounding issues, some survey files couldn't be merged even though they used the same floor plan image and scale.

• Half Power Beamwidth Antenna Types Are More Effective

  For Predictive Surveys, the effect of the horizontal and vertical rotations for half power beamwidth antennas wasn't strong enough. And the rotations didn't match the documentation. These issues have been fixed.
